We encourage our customers to communicate their needs and strive to develop solid working relationships. We are always interested in hearing ideas on how we may improve our products or our services.


Our mission is to manufacture the highest quality parts at a fair price with on-time delivery. In order to achieve your acceptance and to continue our record breaking sales, we promise to strive toward the following goals:

Custom Manufacturing

"Special is Standard" at S4J; nearly fifty percent of our efforts are devoted to custom parts and assemblies. Designs for custom parts are treated as confidential material. Learn more about our Custom Manufacturing capabilities.

Our Facility

S4J Manufacturing Services, Inc. operated in New Jersey for 35 years. In September of 1999 we relocated to Cape Coral, Florida. Our new facility was designed around the product lines we manufacture, complete with the ability to finish in house our brass components which are electroless nickel plated. The result is a dedicated facility for the manufacture of fittings from bar stock to completed, ready to ship, components.
